A 10 watt 12 volt halogen spotlight works pretty well and gives color vision to a couple of hundred yards with nearly any low power scope and even with metallic sights. It's much cheaper than a Gen 3 nightvision scope and gives better resolution. Some states do have pesky laws. In some a light or NV is ok but you can't shoot at all after a certain time after the sun sets. Check your state laws.
No conventional scope can the image have an apparent surface brightness higher than the naked eye image, but up to a 10x scope with an objective 10 times larger then you're eyes pupil) can give more resolution than without a scope. The dark adapted eye has only about 1/10 the resolution of your color vision because the sensors (rods) are thinly distributed compared to the color cones. That's just the nature of optics and has nothing to do with the brand of scope. Most young human eyes are around 7mm maximum aperture but get smaller with age. A scope larger than 50mm and more then 10x magnification won't do us old guys any good, not not much good for anyone.
Do some experiments to see what scope settings actually let you see best in low light.
I'd suggest doing the tests on a moonless light setting eyechart at different distances from a constant white light source. For me a 10X50 is best if I don't need fast target acquisition too. If you do then less magnification and a smaller scope will do. I don't think brand matters much as long as it has decent coatings on all lenses. That does matter. The ability to see (and recognize what your seeing) depends on image brightness, image scale, and the resolution of the optical system. including and especially your eyes .
